Abstract
An optical imaging system includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens sequentially arranged from an object side. At least two of the first lens, the second lens, the third lens, the fourth lens, the fifth lens, and the sixth lens include at least one inflection point. An object-side surface of the sixth lens is concave.
Claims16
An optical imaging system comprising:
- a first lens, a second lens, a third lens comprising a concave image-side surface, a fourth lens having positive refractive power, a fifth lens, and a sixth lens sequentially arranged from an object side, wherein
- at least two of the first lens, the second lens, the third lens, the fourth lens, the fifth lens, and the sixth lens include at least one inflection point, and
- an object-side surface of the sixth lens is concave,
- wherein the second lens has a refractive index greater than a refractive index of the first lens, a refractive index of the third lens, a refractive index of the fourth lens, a refractive index of the fifth lens, and a refractive index of the sixth lens.
